河南省森林固碳释氧效益年际变化研究

按照森林生态系统服务功能评估规范,分不同林分类型对河南省森林的固碳、释氧动态进行了研究。结果表明:全省森林总固碳量及其价值、总释氧量及其价值的年际变化情况一致,即在2006年都是最小,2007—2009年都连续增加。而不同类型林分的固碳量及其价值、释氧量及其价值的变化是不同的;不同类型林分单位面积固碳量是不同的,单位面积释氧量也不同;不同类型林分单位面积释氧量与固碳量由大到小排序一致。

A study on annual changes of carbon sequestration and oxygen release effectiveness of Henan forest

According to the specifications for assessment of forest ecosystem services in China,the dynamic changes of carbon sequestration and oxygen release effectiveness of different types of forests in Henan Province were studied.The results showed that: the total amount and value of carbon sequestration of forests in Henan Province were the smallest in 2006,they were all increased year by year form 2007 to 2009.The total amount and value of oxygen release of forests in Henan Province had also the same situation.Both amount and value of carbon sequestration and amount and value of oxygen release in different forest species had different annual changes.The carbon sequestration of per unit area of different types of forest was different,the oxygen release of per unit area of different types of forest was the same.The carbon sequestration and oxygen released of per unit area of different types of forest had the same descending order.
